    Description: The Verde River watershed in central Arizona furnishes municipal, industrial, and agricultural water to the Salt River Valley --an area that contains more than half of Arizona's population and about one-fourth of the State's irrigated land. Water-management decisions related to the operation of large multiple-use reservoirs require accurate and continuous monitoring of moisture conditions over large remote areas. The U.S. Geological Survey in cooperation with the Salt River Valley Water Users' Association installed a specially designed gaging station on the Verde River near the town of Camp Verde to evaluate near-real time streamflow data furnished by the ERTS-1 Data Collection System (DCS). On Nov. 3, 1972, the installation was equipped with a Stevens digital water-level recorder, modified for telemetry, and an ERTS-1 data collection platform operating in the digital-parallel mode.

    Description: The author has identified the following significant results. The DCS water-stage data from the USGS streamflow gaging station on the Verde River near Camp Verde furnished information sufficient for the accurate computation of daily mean streamflow rates during the first 2 months of operation. Daily mean flow rates computed from the DCS data agreed with those computed from the digital recorder data within + or - 5% during periods of stable or slowly changing flow and within + or - 10% during periods of rapidly changing high flow. The SRP was furnished near-real time DCS information on snow moisture content and streamflow rates for use in the management and operation of the multiple-use reservoir system. The SRP, by prudent water management and the use of near-real time hydrologic data furnished by microwave and ERTS DCS telemetry, was successful in anticipating the amount of flow into the Salt and Verde Rivers and in the subsequent release of water at rates that did not create flooding in metropolitan Phoenix. Only minor flooding occurred along the Gila River west of Phoenix. According to the Maricopa County Civil Defense agency, wage and salary losses of about $11,400,000 resulted from closing of roads across the Salt River in the winter and spring of 1972-73; however, the number and duration of the closing were minimized by use of DCS data.

    Description / Table of Contents: RAMAN and IR-spectroscopic Investigation of Alkyl Derivatives of Arsenic Acid. III. The Vibrational Spectra of Methane and Ethanearsonic Acid and Sodium Hydrogenmethanearsonate.The RAMAN spectra of CH3AsO3H2, C2H5AsO3H2 CH3AsO3HN2. 3/2 H2O (solid and in concentrated aqueous solution) and the IR spectra (400 -4000 cm-1) of these solid acids - partially deuterated - and of the hydrogenarsonate are discussed. The very probable symmetry of these compounds is Cs. As the IR spectra show (two strong broad OH valence bands at 2820 and 2350 cm-1; OH deformation frequency at 1220 cm-1), rather strong H-bonds exist in these acid substances.
    Notes: Es werden die RAMAN-Spektren von CH3AsO3H2, C2H5AsO3H2 und CH3AsO3HNa · 3/2 H2O (fest und in gesättigter bzw. konzentrierter wäßriger Lösung) sowie die IR-Spektren (400-4000 cm-1) der festen, zum Teil deuterierten Säuren und des Hydrogenarsonates mitgeteilt und diskutiert. Diese Verbindungen weisen mit sehr großer Wahrscheinlichkeit die Symmetrie Cs auf. Aus dem IR-Spektrum (zwei starke, breite OH-Valenzbanden um 2820 wad 2350 cm-1, die OH-Deformationsschwingung um 1220 cm-1) muß auf die Ausbildung ziemlich starker Wasserstoffbrückenbindungen geschlossen werden.

    Description / Table of Contents: Raman and IR-spectroscopic Investigation of Alkyl Derivatives of Arsenic Acid. IV. Vibrational Spectra of Some DialkylarsinatesThe Raman and IR spectra of the Na and K salt of the dimethyl- and diethylarsinic acid (in part as hydrate) are discussed. The skeleton C2AsO2- shows very probably the symmetry C2v.

    Description / Table of Contents: RAMAN and IR Spectroscopic Investigation on Alkyl Derivatives of Arsenic-Acid. V. Vibrational Spectra of Dimethyl and Diethyl Arsinic Acid and their Reaction Products with HClThe RAMAN and IR spectra of (CH3)2AsO2H-partially deuterated-and (C2H5)2AsO2H and of the reaction products of these acids with HCl (solid and in concentrated aqueous solution) are discussed. The symmetry of the R2AsO2H skeleton is Cs. of the [R2As(OH)2]+ ion very probably C2v. Whereas (CH3)2AsO2H gives with HCl only a compound (CH3)2ACO2H · HCl (connected by H bonds), the weaker (C2H5)2AsO2H is able to form a salt [(C2H5)2As(OH)2]Cl. The H bonds in the substances are discussed.
    Notes: Es werden von (CH3)2AsO2H (zum Teil deuteriert) und (C3H5)2AsO2H sowie von deren Reaktionsprodukten mit HCl die IR- und RAMAN-Spektren, fest und in konzentrierter wäßriger Lösung, mitgeteilt. Das Dialkylarsinsäuregerüst besitzt die Raumgruppe Cs, das Arsinatacidiumion mit großer Wahrscheinlichkeit C2V. Während die Kakodylsäure mit HCl lediglich ein Anlagerungsprodukt (CH3)2AsO2H · HCl (Bindung über H-Brücken) ergibt, vermag die schwächere Diathylarsinsaure ein Acidiumsalz [(C2H5)2As(OH)2]Cl zu bilden. Die Wasserstoffbrücken in den Verbindungen werden diskutiert.
